Abstract
Изобретение относитс к технике безопасности , а именно к оптическим элементам защитных щитков, защитных очков, предназначенных дл защиты глаз и/или лица работающих от воздействи инфракрасной , ультрафиолетовой радиации, слеп щей ркости и других вредных оптических излучений. Цель изобретени - расширение спектрального диапазона защиты и снижение фоновой засветки в сторону глаз и лица. Оптический элемент содержит пластины 21 и 2 из оптических материалов, активированных люминофорами. Причем спектральна полоса поглощени люминофоров соответствует определенной области спектра вредного оптического излучени , а между пластинами 2 и 2 оставлены воздушные промежутки 3. 1 з.п.ф-лы, 2 ил.This invention relates to safety engineering, in particular to optical elements of protective shields, goggles designed to protect the eyes and / or persons working from exposure to infrared, ultraviolet radiation, glare and other harmful optical radiations. The purpose of the invention is to expand the spectral range of protection and reduce background illumination in the direction of the eyes and face. The optical element contains plates 21 and 2 of optical materials activated by phosphors. Moreover, the spectral absorption band of the phosphors corresponds to a certain region of the spectrum of harmful optical radiation, and between the plates 2 and 2 there are left air gaps 3. 1 Cp. Of the file, 2 ill.
